Summary...
One stage across all scales: Minkowski + 1 (an added full-scale spatial dimension) as a shared geometric setting from the Planck regime to cosmology.What stays fixed: GR remains the tested local limit on the 3D slice; quantum predictions remain the benchmark.Cosmic acceleration: treated as curvature relaxation as 3D space unfolds into the added spatial dimension-without a dark-energy substance.Moderation: required to avoid runaway expansion; physical origin unknown and treated as an open geometric coupling.Dark-matter-like gravity: from curvature distributed into the added dimension plus a speculative CP-violating antimatter pathway leaving a primarily gravitational/spatial remnant.QM-geometry connection: Hilbert space as a projection language for deeper geometric degrees of freedom; some randomness/decoherence may reflect microscopic 3D-4D exchange.Validation: fit expansion history, lensing, and structure growth at ΛCDM precision, and seek distinctive lab/observational signatures.
About / ContactFrank HafnerStaff Scientist Emeritus, Naval Ocean Systems Center (now NIWC Pacific)Email: fifthspacetimedimension@gmail.comI’ve been thinking about these questions since I was about six years old. I’m now in my mid-70s, and this website is my attempt to put a lifetime of curiosity into a form that can be read, criticized, and tested. My goal is to spark the kind of creativity that helps make fusion power and practical quantum computing possible, while also suggesting a different geometric approach for how physics might move past the Standard Model.Underlying that is a lifelong motivation: I’d like to see scientific and technological progress translate into broad, shared benefit-not primarily into accelerating wealth concentration. If this work contributes even a small push toward ideas that are both scientifically useful and socially constructive, it will have been worth doing.
